4 Claims.

This invention relates to a garbage reducing machine for shredding, pulverizing, and emulsitying garbage which may include bones or other solid substances; the improved machine being of such construction that not only is the garbage well disintegrated but the grease contained in the garbage will be emulsified with water which may be introduced into the machine in an effective manner.

In the accompanying drawings Fig. 1 is a plan view of the improved machine. Fig. 2 is a cen tral vertical section of one form of the invention. Fig. 3 is a central vertical section showing a slightly difierent casing construction from that shown in Fig. 2, and Fig. 4 is a detail view of a part to bereferred to.

Referring to the drawings, 12 denotes the body of the machine which aflords a chamber for the reception of garbage which may be fed thereto through a hopper 13 which may be integral with or secured to the body 12, said hopper having a side opening serving as an entrance into the chamber of the body 12. The machine comprises a hollow base 14 surmounted by a casing 15 on which the body 12 is supported in any suitable manner. In the construction shown in Fig. 2 the casing 15 is shown as being bolted to the base 14 and said casing 15 is shown as being bolted to a ring 16 which is, in turn, bolted to the casing or body 12. In the construction shown in Fig. 3 the base 14 and casing 15 are shown as being integral and the body 12 is shown as being bolted to the casing 15.

Attached to thetop of the hopper 13 is a hollow ring 17 into which opens a pipe 18 through which water may be introduced into said ring. The base of the ring 17is provided with a circular series of openings 19 disposed closely adjacent to the vertical plane of the inside walls of the hopper, and through which openings water may flow so that it will trickle down the inside wall of said hopper and thus facilitate the downward passage of garbage in said hopper. The ring 17 may have a hinged cover 1'! which can be thrown back when the hopper 13 is to be filled.

The casing 15 is provided with hearing portions 20 and 20 in which is journalled a shaft 21 provided at one end with a coupling member 22 splined to said shaft and adapted to be joined to a driving member. Keyed to the shaft 21, within the central portion of the casing 15, are steel disks 23 provided with peripheral teeth 24, these disks 23 alternating with spacing disks 25. The shaft 21 is provided with a flange or fixed col-.

lar 21 between which and a nut 21 the disks 23 and 25 are clamped.

The shaft 21 is constructed at its end opposite the coupling member 22 with a hexed or noncircular part 21 extending into a recessed part of the bearing member 20 so that a crank can be fitted to said shaft to turn the same, when desired, as, for example, in case the rotor, comprising the disks 23 and 25, should become jammed.

Attached to one side of the base 14 and casing 15 is a plate 26 (see Figs. 3 and 4) provided with a series of spaced-apart teeth 27 which register with the disks 25 so that the teeth 24 on the disks 23 can pass between them, these teeth 27, which face opposite the teeth 24, assisting in the grinding and reducing of the garbage. Attached to the plate 26 is an inclined pipe 28 communicat-ing with an inclined opening through said plate, the exit of said opening being adjacent to the grinding rotor, so that water introduced un der pressure through the said pipe 28 will serve to clear the said rotor of any material which might adhere thereto.

The topof the body 12 is provided with an opening for the reception of a push rod 29 adapted to extend down into the chamber of the body 12 for feeding down light material, such as lettuce and cabbage leaves. The opening through which the push rod extends may be closed, when the push rod is not in use, by a swinging cover plate 30.

To prevent the rotor from throwing out bones or other hard substances, when the machine is in operation, the inside wall parts 13 of the hopper are preferably inclined, as shown in Fig. 2, so as to have a tendency to deflect any material which may be thrown against them back into the chamber of the body 12.

The upper part of the casing or body 12 is preferably curved or rounded transversely, as clearly shown in Fig. 3, thus affording a chamber which is transversely curved at its top and in which the garbage which is being reduced may circulate more or less and be returned to the grinding rotor, as denoted by the arrows on Fig. 3, circulation of the garbage in the chamber of said casing or body being induced by said rotor.

This storage and circulating chamber, into the side of which, or laterally, the hopper 13 opens below the top of said chamber, is an important feature of my invention, in that it facilitates the feed of the garbage to the grinding rotor and the circulation of the garbage in said chamber, and also affords means for the insertion of the push rod 29 which may be used when necessary to prevent the machine from clogging. The circulation of the garbage in the storage and circulating chamber is facilitated by the water which may be supplied to the hopper through the hollow ring 17 surmounting said hopper, the water thinning the garbage somewhat, so that it may circulate more readily, as will be obvious.

Having thus described my invention I claim and desire to secure by Letters Patent:-

1. A garbage reducing machine comprising a hollow casing or body which is transversely curved at its top affording a circulating storage chamber transversely curved at its top, said top being provided with an opening for the insertion of a push rod, a hopper arranged at one side of said casing or body and opening into said chamber, a casing supporting casing or body and hopper, a hollow base on which said last-named casing is supported, a shaft journalled in said last-named casing, and a grinding rotor carried by said shaft.

2. A garbage reducing machine comprising a hollow casing or body which is transversely curved at its top to afford a circulating chamber, a hopper arranged at one side of said casing or body and opening into said chamber, a casing supporting said casing or body and hopper, a hollow base on which said last-named casing is supported, a shaft journalled in said last-named casing, a series of spaced grinding disks, provided with peripheral teeth, keyed to said shaft, and a plate fixed to said last-named casing and provided with teeth facing oppositely to said peripheral teeth, said plate having an inclined opening for supplying water to the rotor comprising said shaft and disks.

3. A garbage reducing machine comprising a hollow casing or body which is transversely curved at its top affording a circulating storage chamber transversely curved at its top, a hopper arranged at one side of said casing or body and opening into said chamber, a hollow casing supporting said casing or body and hopper, a hollow base on which said last-named casing is supported, a shaft journaled in said last-named casing, a series of grinding disks, provided with peripheral teeth, keyed tosaid shaft, and spacing disks also keyed to said shaft and alternating with said grinding disks, said chamber, into the side of which said hopper opens, being above the chamber afforded by said hollow casing and in which last-named chamber said grinding disks are located.

4. Apparatus for the purpose set forth comprising a casing, a hopper mounted on and rising from the casing and having a vertically extended inlet opening in one side, a branch hopper rising from the side of the hopper around said inlet opening and provided with an annular chamber at its upper end, means for supplying running water to said annular chamber and to the casing, a rotatable pulverizing roll mounted within the casing, and stationary blades on the side of the casing co-operating with said roll.
